EXPERIMENT AND THERMODYNAMIC ANALYSIS ON THE PHASE STABILITY OF LOW ACTIVATION Fe-Cr-Mn(W, V) ALLOY

Keywords： phase stability

Phase stability of four different chemical component Fe-Cr-Mn(W, V) alloys are in-vestigated by experimental method and thermodynamic model in this paper. It is indi-cated that the main phase of four alloys after aged under 623, 673, 773K for 200h areaustenitic phase. The results of Thermo-Calc, which are based on Gibbs energy, showthat the phases of four alloys underthe same temperature as experimental method aresingle austenitic phase. The results of experimental method and Thermo-Calc agreewell.
